Specification of Letters Patent.

Patented June 1'7, 1919.

Application filed May 18, 1916. Serial No. 98,468.

Toall whom it may concern:

Be it known that I, JACQUES MAYER, a citizen of the United States of America, re siding at Kurfurstendamm 181, Berlin, Germany, have invented new and useful Improvements in Apparatus for Automatically Operating Typographical and other Selectively-Operated Machines, of which the following is a specification.

This invention relates to apparatus for auton'iatically operating typographical and other selectively operated machines.

with, and is hereinafter for convenience described as applied to, typographical composing machines such as those known commercially under the trade mark Linotype, wherein the release of matrices, type-dies or the like from the magazine in which they are stored, is normally effected by mechanism controlled from a manually operated keyboard. It has heretofore been roposed to automatically operate such mac ines by means of mechanically, electrically or pneumatically actuated devices, acting either directly on the keys or on other organs connected with the matrix-releasing devices, and controlled by means of a paper strip having perforations corresponding to the keys to be struck or matrices to be released. The operation of such devices has usually Iinvolved the provision of either a great number of electric or pneumatic conductors which are diflicult to 1nspect,,or direct and complicated lever connections, between the paper strip and the keys or releasing devices to be actuated. v

According to the present invention, the

-just-named disadvantages are eliminated,

and the operation of a large number of keys or releasing devices through the medium of a small numb r of pneumatic conductors is rendered possible by the use of a special device interposed between the perforatet strip and the striking devices,

in conjunction with an improved system of perforations on the strip according to which two such perforations are employed for the actuation of each striking device. In addition to providing these improved means for actuating the matrix-releasing devices, the pix-sent invention also includes mechanism,

under the control of the perforatedstrip,v which elevates the assembler, wherein the.

It is especially applicable for use in connection matrices are composed in line, in order to permit the removal of a completed line therefrom, and returns it to its line-receiving position, and means for preventing the automatic operation'of the matrix-releasing devices in the event of the assembler failing to return to the last-mentioned position.

. The invention will now be described with reference to the accompanying drawings, which illustrate a constructional form thereof as applied to a matrix-composing machine, and in which Figure l is a side elevation of the apparatus, partly in section, and showing diagrammatically the relevant parts of the matrix-composing machine;

Fig.4 a front view of the controlling device with the conductors removed, and partly in section;

' Fig. 5 a sectional plan taken on the line 55 of Fig. 4; and

/Fig. 6 a detail view of the striking devices.

Referring to Fig. 1, part of the frame of the matrix-composing machine adjacent to the keyboard thereof is indicated at 1, 2 being a part of a key-lever, which on the depression of the key, raises the respective key rod 3, thereby releasing the so-called -'cam-yoke to bring the cam 4 into contact with the constantly rotating roller 5 which,

acting through the cam-yoke, raises the escapement reed 6 whereby the escapement is actuated and amatrix released from the respective channel of the magazine. All the escapement-actuating devices just referred to are of well-known construction, and operate in the known manner. As a convenient means of employing the automatic actuating strikers 8, as shown in detail in Fig. 6, constitutes the upper end of a piston working in a cylinder 9, which cylinder is connected by a conductor or pipe 10 with the special controlling or distributing device provided according to the present invention.

The construction of the controlling device is best illustrated in Figs. 3, 4: and 5 of the drawings. Broadly speaking, itconsists of a frame 13 having a number of" pneumatic channels and ports, connected, in a manner hereinafter more particularly described, on the one hand with a pneumatic pressure supply controlled by a perforated strip, and on I the other with the above-described cylinders 9.

The above mentioned conductors 10 connecting the cylinders 9 with the controlling device, communicate with the latter through openings or ports 11 in front plates 12 se cured to the frame 13 by screws 14.' Three such front plates 12 areshown in the drawings,,but any other suitable number of such plates of convenient size could be substituted therefor if desired. The ports 11 are arranged in rows or groups, vertically as well as horizontally, and in the arrangement illustrated there are six horizontal roWS or groups and seventeen vertical rows or;

groups, comprising in all one hundred and two ports. Behind each horizontal row or group of portsll, there is a control bar or valve 15, which is, capable of sliding in a groove in the frame 13. Each of the six control bars 15 is provided with openings corresponding in number and relative position with the ports 11 in the respective horizontal row, by means of which, -accord-.

ing to the position of the bar 15, connection is established or prevented between the ports 11 and corresponding ports 16in the frame 13. All the ports 16 in one vertical row or group communicate with a common vertical channel or chamber 17 in the frame 13, and each of the seventeen vertical channels 17 is connected by a conducto 18 with a common tracker bar 19 over which the perforated strip 20 is traversed, as shown in Fig. 1.

Due to. their connection to the ports 11, the conductors 10 may be regarded as divided into similar groups; that is to say,

the conductors connected to the ports of thevertical rows constitute a plurality of grou s, each of which is supplied with the weenie fluid pressure from a single conductor 18 through the medium of the common conmeeting or distributing channel 16, while in another sense those conductors 10 connected to the ports of the horizontal rows constitute a. plurality of groups in each of which one conductor is connected to each of the channels 16.

Each of the control bars 15 is fast at one end .to a piston 21 working in a cylinder 22 formed in a block 23 secured to the frame 13, and is normally held in its left-most position, wherein its holes are out of register with the orts 11 and 16, as shown in connection with the top Or first, third fourth, fifth and bottom bars in Figs. 3 and 4, by a spring 24 acting between the piston and the respective end of the cylinder 22. The movement of a bar to the right, to the posi- -tion in which the bar represented in Fig. 5

is shown, with the holes in'the bar in register with the ports 11 and 16, is efiectediby pneumatic pressure, supplied through a cbnductor 25 leading from a port in the respective cylinder 22 to the tracker bar 19, which ated strip 20, which is stored on a spool 26,

and in known manner carried therefrom over the tracker bar 19,- and wound, with an intermittent motion derived by any suitable means from the constantly rotating-shaft 27, on to a second spool 28, each intermittent forward movement of the strip bringing a combination of perforationscorresponding t0 the matrix-releasing device to be actuated into register with the ports on the tracker bar communicating with the respective conductors 18, 25. Compressed air is supplied, from any suitable source, through a valve 29 to a pressure chamber 30 which communi cates with a mouthpiece 31, so that when the mouthpiece is, as next to be described, moved down into air-tight contact with the perforated strip, compressed air is admitted therethrough to the particular conductors determined by the strip perforations then lying over the tracker bar ports, there being two such perforations for each matrix releasing device, one to'admit pressure to a conductor 18, and the otherto admit ductor 25.

The movement of the pressure chamber 30 to bring the mouthpiece 31-down on to the paper strip, is accomplished by ajcam 33 fast to the before-mentioned constantly rotating shaft 27 which is driven by a belt 3 1 from a pulley 74 on the main shaft 35 as will be hereinafter explained. A roller 36 on a lever 37 fulcrumed at 38 on the frame pressure to a conupper side of the latter in a head 32.

39, is held in contact with the cam 33 by a spring 40. The lever 37 is connected to the pressure chamber 30 through a link 41 and a lever 42 pivoted to an upstanding arm '43 which is itself pivoted on the said frame at 44, and is integral with an arm rigid upon the pressure chamber 30. Arod 122 screwed or otherwise rigidly secured to a' lug 46 on the pressure chamber 30, passes loosely the valve 29. When the lever 37 is de-v pressed by-the cam 33, against the influence of the spring 40, the lever 42 is depressed so as, through the spring 45, to resiliently hold the mouthpiece 31 in airtight contact with the perforated strip 20 and at the same time, through the set-screw 47, open the valve 29 and thereby admit compressed air into the said mouthpiece. As soon as-the rotation of the cam 33 has caused the lesser radius thereof to be presented to the roller 36, the spring 40raises the. lever 37 which through the link 41, raises the lever 42 together with the set-screw 47, thus allowing the valve 29 to close (under the action of a spring or the pressure of the air). The continued upward movement of the. lever 42 brings the latter into contact with the head 32, after which this lever together with the pressure chamber 30 and upstanding arm 43, rock as a complete entity about the pivot 44 I so as to raise the mouthpiece 31 out of conshown in Fig. 5), and by the consequent tact with the perforated strip 20.

The manner inwhich the strikers 8 are operated will now be understood. Immediately after the strip 20 has received a forward movement the cam 33 acts on the lever 37 and brings the mouthpiece 31 down into close contact with the strip 20 at the same time causing the opening of .the valve 29 and the admission of compressed air into the mouthpiece 31 whence it passes through the.

two strip-perforations then in operative position, into the respective conductors 18 and 25. The pressure in the conductor 25 moves the respective piston 21 to the right (as movement of the appropriate bar 15, establi'shes ,a connection between all the ports 16 and 11 in one horizontal row. The pressure'in the conductor 18 is led into the respective channel 17, which, as above de these means, in the example illustrated, 102

matrix-releasing devices can be operated by 23 conductors connected with the tracker bar. 1

As thus far described, the apparatus deals only withthe release of matrices from their magazines. In the machine to which the invention is herein shown as applied, the matrices, when so released, are assembled in line in an assembler 48, and when a complete line has been composed, the assembler is raised so that the line may be removed therefrom by a line carriage 49, and thereafter lowered again into position to receive the next line to be composed. The raising and lowering of the assembler is effected automatically according to the present invention, under the control of the perforated strip, by the mechanism illustrated in Figs. 1 and 2 of the drawings and now to be described.

A special pair of perforations, adapted to admit pressure to a conductor 50, are ar- 1 scent of the mouthpiece 31 and opening of the valve 29, compressed air will be conveyed beneath a piston 51, which will be thereby raised. The piston acts on the horizontal arm of a bell-crank lever 52, fulcrumed on a lug 53 extending from one of the standards supporting the main shaft 35 previously referred to. The said shaft 35 is hollow, and has mounted within it a rod 54, an extension of which is embraced by the forked upstanding arm of the bell-crank lever 52 which, acting between two collars 55, 56 on the rod, is capable of moving the latter axially relatively to the shaft 35.

The main driving pulley 57 is freely mounted on the main shaft 35, and is constantly driven by a belt 58 from the driving motor of the machine; it is provided with clutchteeth 59 adapted to engage a clutch 60 which is secured to the rod 54 by a pin 61 passing through horizontal slots in the said shaft, so that axial movement of the rod 54 will be transmitted to the clutch 60 and result in the rotation or stoppage of the shaft 35 by the connection of that clutch with or its disconnection from the pulley 57.

When the bell-crank lever 52 is actuated by the piston 51, as above-mentioned, the rod 54 will be moved to the'left, into the position, in which it is shown in Fig. 2, the clutch 60 will be thereby thrown into gear with the clutch-teeth 59 on the pulley 57, and the shaft 35 will be rotated untll the clutch is again disconnected. v

Fast on the shaft 35 is a spur pinion 61,-

meshing with a ear wheel 62 secured on a shaft 63, which a lso has fast on it a cam or eccentric 64 engaging a roller 65 of a lever 66, which lever, acting through a link 67, effects the raising of the assembler 48. One half a rotation of the cam 64 raises the assembler to its line-delivering position, and during the next half-revolution the assembler is allowed to return to its line-receiving position. Consequently, only one complete rotation of the shaft 63 is required for the desired movement of the assembler, and for the purpose of stopping the rotation of the shafts 35 and 63 on the completion of one revolution of the latter, there are provided a collar 68 loosely encircling the shaft 35 and secured to the rod 54 by a pin 69 passing through longitudinal slots in that shaft; and a lever 70, fast to a shaft 71 rocking in bearings mounted on the base plate of the apparatus, and extending into the path of a projection 72 fast to the respective side of the gear wheel 62. When the rod 54 is moved to the left (Fig. 2) to throw in the clutch 60, it carries with it the collar. 68,

which is brought into contact with a nose 73 on the lever 70. The projection 72 is so positioned on the gear wheel 62 that, on the completion of one rotation of the latter, it comes into contact with the upper end of the lever 70, forcing that end toward the right, and through the nose 73 and collar 68, moves the rod 54 to the right, thus disconnecting the clutch from the pulley 57, and stoppin the rotation of the shaft 35.

he before-mentioned pulley 74 is loose on i the shaft 35, and is engaged by clutch teeth 75 with the pulley 57, with which it is normally held in contact by a spring 76 bearin between it and a collar 77 fast on the sha t 35. It will thus be seen that the rotation of the pulley 74, and consequently the movement of the strip 20, is not interfered with during the raising and lowering of the assembler, but, as there will be no perforations on the portion of the strip 20 which passes over the tracker bar 19 during that operation, no matrices will be released, The unperforated portion of the strip, however, will only extend over as much of the strip as will be traversed over the tracker bar during the period occupied by one rotation of the gear wheel 62. Consequently, if the assembler should for any reason fail to return to its line-receiving position during that period, composition would be automatically resumed, but wouldbe ineffective owing to the inability of the assembler to receive the released matrims. Any such improper release of matrices is prevented, in the event of the assembler failing to descend after having delivered a line by the following devices.

A plate 78 is mounted on the shaft 63 by a slotted bearing 79 and secured to the cam 64 by screws 80 passing through slots in the plate, to enable it to rotate with the said cam, with a capacity for moving radially relatively to the axis of rotation. One end of the plate 78 is-in contact with a lever 81 pivoted on the cam 64 at 82 and constantly urged against that end of the plate by a blade spring 83 fast to the cam 64, tending to move the' plate radially and protrude its outer edge beyond the periphery of the cam 64. Pivoted on a shaft 84 mounted in brackets 85 on the base plate of the apparatus, is a bell-crank lever 86, 87, the upstanding arm 86' of which is provided with a T-head 88 extending, in one direction, toward the cam 64, the other arm 87 being normally held, by a spring 89, in the path of a lever 90 in such a way as to prevent the latter moving to the right (Fig. 2), about the axis of a rocking shaft 91 to which it is fast, under the action of a spring 92. The connection of the lastmentioned spring with the lever 90 is not shown in the drawings, as the respective part of the said spring is represented in Fig. 2 as broken away for the sake of clearness. The lever 81 is provided with a lateral projection 93 which, under certain circum-' stances, is capable of engagin with the head 88 on the lever arm 86. n the position in which the parts are shown in Fig. 1, the assembler is in its lowest position, the roller 65 on the lever 66, serving to keep the plate 78 depressed against the action of the spring 83, and the lever 81 in such a position that onthe subsequent rotation of the cam 64, its projection 93 will clear the head 88. This relative position of the plate 78 will be maintained until the rotation of the cam 64 permits the spring 83 to act and, through the lever 81, protrude the plate 78 beyond the periphery of the said cam; but by that time the projection 93 will have passed the head 88 without coming into contact with it.

shown in Fig. 1, immediately after which the projection 72 on the gear wheel 62 will act, as above described, to stop the rotation of the shafts 35 and 63. If, however, the assembler should fail to descend, the plate 78 will be maintained in its protruded position, and, before the projection 72 can act, the projection 93 on the lever 81 will come into contact with the head 88 moving the latter toward the right in Fig. 1, and raising the lever arm 87 clear of the lever 90, thus permitting the latter to be moved by the spring 92. As shown in Fig. 2, shaft 91 has fast on it an upstanding arm 90 which moving the lever 81 again into the position i obstruction to the proper descent of-the assembler can then be removed, and the levers reset ready for the operation of the machine to be resumed. For this latter purpose, a

\"hand lever 96 (seen only in Fig. 1) is provided fast on the shaft 91, by which that shaft can be rocked in order to return the lever 90 against the action of the spring 92. Before this return movement of the lever 90 takes place, the lever 86, 87 will have been returned to its normal position under the influence of its spring 89, by the readjustment of the plate 78 and the consequent disengagement of the projection 93 from the head 88. The lever arm 87 will therefore stand in the path of the returning lever 90, and is arranged to act as a latch, lifting to allow the lever 90 to pass, but immediately thereafter locking the said lever against the action of the spring 92. The slot-and-screw connection 95 between the link 94 and lever 7 0, permits the latter to rock when acted upon by the projection 72 or collar 68 without afi'ectingthe lever 90 and the coiiperating parts.

To insure that vthe cam 64 shall come to rest in the correct position when the clutch 60 is thrown out, a lever 97 is mounted on the before-mentioned shaft 84, one arm of which is provided with a roller 98 kept constantly in contact with the periphery of the cam 64 by a spring 99 acting on the opposite arm of the lever. The cam 64 is provided with a notch 100 which, in conjunction with the roller 98 engaging therewith when the cam reaches its position of rest, acts as a yielding stop to assist the weight of the parts in preventing overrunning of to the free end of the said lever, and has a boss 102 on its opposite end encircling the lower end of the link 67, the lift of the lever 66 being transmitted to that link through a spring 103 arranged between the boss 102 and a collar 104 on. the link. If the assembler 48 is prevented from leaving its linereceiving position, or is arrested before reaching its line-delivering position, the lever 66 is by these means permitted to continue its upward movement for a short distance, while the link 67 remains at rest. A bell-crank lever 105 is pivoted at the free end of the lever 66, one arm of which extends beneath the end ofthelink 67 protruding through the boss 102, the otherarm being connected by a link 106 to one arm of a bent lever 10? pivoted on a stud-shaft 108, on which is also fulcrumed the lever 66. The second arm of the bent lever 107 is connected by a link 109 to an arm 110 operatively fast to the lever 86,.87. When the lever 66 moves upward while the link 67 remains at rest (which movement occurs in the event of-the rise of the assembler 48 being obstructed as above-mentioned), the lower end of the link 67 causes a movement of the bell-crank lever 105 about its pivot, which movement is transmitted, by the link and lever connections just described, to the lever arm 87, whereby, in the manner previously described, the apparatus is stopped by theaction of the spring 92 on the levers 90 and 70.

The present invention further provides means for stopping the automatic operation of the assembler elevating and matrix-releasing devices in the eventof the line carriage 49 not being-in a proper position to receive the line from the. assembler 48. These means consist of a bell-crank lever 111 pivoted to one side of the gear wheel 62; a pin 112 pivoted to one arm of the lever 111 and normally protruding through an opening in the gear wheel 62, and a rod 113 depending from one arm of a bell-crank lever 114 the upstanding arm of which is held, against the action of gravity, by the line carriage 49, when this latter is in its line-receiving position. Thenormal positionof the pin 112 is such that it will, as the gear wheel 62 rotates come into contact with the head 88 on the lever arm 86, and

thus effect the stoppage of the apparatus in the manner which will now be well understood. The lower end of the rod 113 has a projection which, when the line carriage is in its line-receiving position, is held by the action of the bell-cranklever 114, in the path of the free end of the bell-crank lever 111, and that end of thesaid lever will'be raised by riding over the said projection, thus withdrawing the pin 112 and preventing it contacting with the head 88. If the line carrings is not in its correct position, the rod 113 will remain in a position in which its a In order to enable the apparatus to be stopped by hand whenever it may be desired to do so, a shaft 115 carrying a cam 116 and provided with a handle 117, is mounted in bearings formed in a bracket 118 attached to the base of the frame 13. A rod 119, guided at its upper end in the bracket 118, and at its lower end in a fixed bracket 120, is held in constant contact with the cam 116 by a spring 121, its lower end being in a position to act, when depressed, on the substantially horizontal arm of the bell-crank lever 52; these parts are shown intheir inoperative position in Fig. 2. If the handle 117 is turned 90 from the position there-shown, the cam 116 will depress the rod 119, which, acting through the lever arm 52, will force the rod 54 to the right far enough to disengage the clutch from the pulley 57, and to also effect the disengagement of the pillley 7 4. When the handle 117 is turned back, the reengagement of the pulley 7 4 with the pulley 57 is automatically effected by the spring 7 6, and the composing mechanism is re-started.

It will be readily understood that, although the mechanism is herein described as applied to the operation of n'latrix releas'ing devices and the assembler in a typographical composing machine, it may equally well be applied to matrix-releasing devices and a periodically operated organ other than the assembler, and to other machines, for example, to typewriters, in which casethe striking devices could be arranged to operate on the keys or key levers, and what is herein termed the assembler elevating mechanism could be applied to the purpose of operating the paper carriage. Further, the substitution of a vacuum for compressed air as the operating medium would not present any difficulty. It is, therefore, to be understood that any such application or substitution falls within the scope of the invention.
